March 9, 2021
TO: Mayor & City Council
FROM: Greg Hermann, Deputy City Manager
VIA: Robert Hill, Sustainability & Natural Resources Official
SUBJECT: Pilot Program for Extended Open Space Hours of Use During Winter Months
This memorandum provides a final summary report of wildlife survey results, visitor utilization
rates, and overall observations over the course of the City’s Pilot Program for Extended Open
Space Hours of Use During Winter Months at Cerro San Luis Natural Reserve. The Pilot Program
took place during the winter seasons when daylight savings time is not in effect in 2018-19, 2019-
20, and 2020-21.
The City Council will recall that its final approval of the Pilot Program, following citizen input
and a study session, also included adoption of a Mitigated Negative Declaration environmental
document pursuant to the requirements of the California Environmental Quality Act. This
document concluded that potentially significant impacts to Biological Resources could occur but
would be less than significant with mitigation measures incorporated. These measures are as
follows:
BIO-1 Wildlife Monitoring and Adaptive Management. City staff and biological consultants shall conduct
regular, weekly monitoring and evaluation of both human use and wildlife use of the Reserve. This will be
done by deploying an EcoCounterTM device to track frequency of human use and hours of use at the Reserve,
as well as four wildlife game cameras (Bushnell or similar model), cover boards, detection equipment such
as a bat detector (Petterson D500x), and field surveys to monitor and track nocturnal wildlife composition,
activity, and behavior. Regular evening patrols of the trails within the Reserve by Ranger Service staff will
also provide anecdotal observations.
BIO-2 Wildlife Water Sources. The Reserve features a developed spring proximate to the historic Lemon
Grove. This spring will be used to grav ity feed water to two wildlife-friendly “guzzlers,” or troughs, while
still returning flow to the natural drainage path of the spring. This will provide additional watering sources
that will benefit wildlife by decreasing the level of energy required to fi nd water and decreasing competition
among different species for water.
BIO-3 Public Information and Education Materials. City staff shall develop additional information and
educational materials for the public that is specific to this pilot program. These materials will re-iterate the
City’s rules and regulations in effect, as well as highlight the sensitivity of evening use and potential for
wildlife interactions and impacts. These informational materials will be available on the City’s website, on
the main kiosk at the entrance of the Reserve, and on pamphlets that can be handed out or placed in a rack
on the kiosk.
BIO-4 Evening Use Permitting System. City staff shall develop an online internet-based permitting system
in order to ensure that evening use (from one hour after sunset until 8:30 PM) during the pilot program period
is kept at or below existing average daily baseline use of 65 individuals. Individuals will be required to have
evidence that they have the required permit in their possession. Ind ividuals that are stopped by Ranger
personnel and do not possess a permit will be subject to citation under municipal code section 12.22.050(B).
The City’s Ranger Service and Natural Resources Program staff can confirm that each of these
mitigation measures were carried out, as follows:

1. Wildlife surveys were conducted by qualified biologists with the firm Terra Verde
Environmental during the course of the Pilot Program. In addition, wildlife game cameras
were deployed and monitored by Ranger Service staff and regular field monitoring and
patrol also occurred. Observed wildlife species were numerous and included barn owl,
great-horned owl, sharp-shinned hawk, deer, coyote, woodrats, and mice. Terra Verde’s
reports are included here as Attachment A.
2. An EcoCounterTM device that uses infrared technology to capture use data was installed at
the Marsh Street trailhead in a location chosen to capture single users at a time (as opposed
to multiple hikers or bikers together).

3. Two wildlife watering stations, or guzzlers, were installed by Ranger Service staff
proximate to the Lemon Grove and the eucalyptus grove, together with remote-sensing
wildlife game cameras. Wildlife species observations captured on the City’s cameras over
the course of the Pilot Program were similar in composition to that observed by Terra Verde
Environmental during their field work.

4. Public information and educational materials were prepared and installed at the Marsh
Street trailhead kiosk by Ranger Service staff.
5. A website-based application, or “App” was developed specifically for the Pilot Program
by the firm iiiDesign for interested parties to secure the necessary permit for evening hours
of use. Paper copy permits were also available from the Parks and Recreation Office, or in-
the-field from Rangers when available.
Pilot Program for Extended Open Space Hours of Use During Winter Months Page 5
Additional observations and lessons learned from the Pilot Program are as follows:
1. Overall utilization of the Pilot Program was dramatically higher in December compared to
the other months across all three years. This is very likely due to the holiday lighting that
is placed on the summit of Cerro San Luis, which is not located on the City’s property.
Demand was high enough during these times that people were turned away by Ranger
Service staff, which likely resulted in hikers accessing the mountain from other locations.
There were also numerous instances of non-compliance (individuals tracked with the Eco-
Counter that exceeded the number of permits available). There is a clear year over year
upward trend of overall use and interest in the Pilot Program; this is especially true for year
three during the COVID-19 pandemic. All available permits were issued almost every
night in December each year, compared to a much lower average of permits issued per
night when the lights were not lit up. Rangers also noticed a subjective difference in the
type of user while the lights were up versus when they were not. Users hoping to visit the
lights at the top of the mountain often appeared to be less familiar with the open space rules
and regulations, and less well prepared.
2. There were some minor “glitches” with the permit App during the beginning period of the
first year of the Pilot Program that resulted in the possibility of additional permits beyond
the 65 allowed in total being issued, but this problem was quickly rectified.
3. There was a trend of users of the permit App to inadvertently reserve numerous permits for
the same evening, likely due to hitting the submit function repeatedly, resulting in some
hikers not being able to retrieve a permit that was inadvertently reserved by someone else.
4. A simple web-based survey was sent to all users who were issued a permit. Based on 166
responses, many users were happy with their experience getting a permit and felt that the
expanded hours of use improved their overall experience in Cerro San Luis Natural
Reserve. Others expressed concerns for wildlife and with crowding and associated
impacts. Some people expressed displeasure with the difficulty getting a permit due to the
65 per day permit cap. The majority of users used the expanded hours only 1-3 times while
the program was in effect. About 1/3 of users reported encountering some kind of wildlife
during their night use; the most commonly reported were rat/mouse and owl, while one
user reported seeing a mountain lion.
A final summary of Pilot Program statistics for all three years is included as Attachment B to this
memorandum.

RE: Summary and Results of Wildlife Surveys at Cerro San Luis Natural Reserve,
City of San Luis Obispo, California
The City of San Luis Obispo (City) is considering extending the hours of use for one or
more City open space properties. Of specific interest is Cerro San Luis Natural Reserve
(Reserve) based on location, surrounding land uses, proximity to traffic, and amount of
use currently occurring on the Reserve. Terra Verde Environmental Consulting, LLC
(Terra Verde) was retained to assist the City with gathering data that will help inform
the City's decision-making process for extended use hours of the Reserve.
Prior to conducting the surveys, a review of aerial photography was conducted and a
site visit with City staff occurred on September 8, 2017. Past reports prepared for or by
the City regarding this property were also reviewed (City of San Luis Obispo Natural
Resources; Tenera Environmental 2004).
General Survey Methodology
Terra Verde biologists Brooke Langle and Rhett Blanton conducted the first survey on
September 9, 2017. The survey was conducted along the Lemon Grove Loop Trail with a
visual scan of surrounding areas. During this survey, four coverboards were installed in
two differing habitat types, acoustic monitoring for bats was set up, and spotlighting for
wildlife was conducted. Environmental conditions consisted of partially clear skies, S
mile per hour (mph) winds, and temperatures ranging between 60 and 70° Fahrenheit
(F). Methods for the acoustic bat monitoring are discussed below in further detail.
A second survey was conducted on September 12, 2017 by Ms. Langle accompanied by
staff associate Levi Heit. Coverboards were checked, additional acoustic data collection
occurred, and spotlighting for wildlife was conducted. Environmental conditions

consisted of overcast/foggy skies, 8-15 mph winds, and temperatures ranging between
65 and 70° F.
During the surveys, all species observed directly and/or indirectly (e.g., tracks, scat, call,
remains, and acoustic observation) were documented.
Acoustic Bat Monitoring Methodology
A Pettersson DSOOx bat detector was employed for several hours after sunset during the
two survey periods. The detector was placed along the margins of a eucalyptus row on
the east side of the City's project, near a recently installed water trough. Bats were
observed emerging from the eucalyptus as well as coming up from the residential
neighborhoods downslope. Following field acoustic monitoring, recorded full spectrum
data was analyzed using SonoBat US West (Szewczak). Each bat recording was identified
to species level when possible. Additional acoustic monitoring is planned for the upper,
rocky peak areas of the Reserve.
Wildlife Results
Environmental conditions and anthropogenic activity levels varied between the
September 9 and September 12, 2017 survey efforts. The first survey had mostly clear
skies, warmer weather, and very little human activity noted at the beginning of the
survey and no activity noted after dark. The second survey occurred with high fog cover,
higher wind conditions, cooler weather, and more human activity. On September 12,
the parking lot at the trail head was full and people were observed heading up the
mountain at 6:30 p.m. After sunset and for approximately one-half hour after sunset,
several mountain bikers were observed coming down the mountain with headlamps
illuminated. One flashlight was observed coming down from the peak of Cerro San Luis
Obispo at approximately 10:00 p.m.
Coverboards
Two of the coverboards were placed in coastal sage scrub off the lower Lemon Grove
loop trail. Two additional coverboards were placed under the canopy of a coast live oak
tree and downslope from that board, in a mixed scrub habitat. It often takes a period of
time for coverboards to develop an advantageous microclimate and for species to
discover them. As such, the check of the newly installed coverboards did not result in
finding any species under them. Coverboards remained at the site following the surveys
for follow-up data collection.
Bats
The first night of acoustic monitoring resulted in up to three species of bat being
recorded. The highest confidence recording was of a Mexican free-tailed bat (Tadarida
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
TERRA · VERDE
Environmentol Consulting
brasiliensis), with two poorer recordings indicating hoary bat (Lasiurus cinereus) and
silver-haired bat (Lasionycteris noctivagans). Approximately 10 bats were visually
observed flying over the recording station within the first hour after sunset. Some of
these bats appeared to be flying up the mountain from the surrounding neighborhood.
Mexican free-tailed bats are known to inhabit daytime roosts in the surrounding
neighborhoods, including residential structures (Langle, personal communication).
The second night was less ideal for capturing bat recordings due to windy and cooler
conditions. Only one bat was observed flying above the recording station and no bat
calls were captured by the detector.
Spotlighting
After bat recording was set up and observations occurred during the hour after sunset,
the biologists walked the trail system, stopping frequently to scan up the surrounding
area with high powered flashlights or spotlights. Any eyeshine detected was
investigated and binoculars were used to identify species. The survey occurred up to
three hours after sunset.
The following species were observed during the first spotlighting effort: great horned
owl (Bubo virginianus) roosting in eucalyptus grove above trail, barn owl (Tyto alba)
foraging from top of small cypress tree near trail, American kestrel (Falco sparverius),
deer mice (Peromyscus maniculatus), striped skunk (Mephitis mephitis), and two mule
deer (Odocoileus hemionus). The area around the eucalyptus tree line, the coast line oak
woodland higher up the mountain, and the seep appeared to be more active than the
more open grassland habitats.
The second spotlighting effort resulted in observing: great horned owl (on the edge of
the eucalyptus grove, a coyote (Canis latrans) near the spring, two mule deer, a
mountain lion (Puma concolor), and three raccoons (Procyon lotor).
Wildlife Species Discussion
There are numerous wildlife species that inhabit the Reserve and surrounding areas of
Cerro San Luis. There is a potential for special status species to occur, however, there
are limited records of sensitive species occurring within the Reserve. The report
prepared for the City in 2004 noted the following sensitive species:
•San Diego desert woodrat (federal and state species of special concern)
•Bats, unknown species (local concern)
•Ornate shrew (local concern)
•Raptors (local concern)
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
TERRA · VERDE
Environmentol Consulting
•Yellow-rumped warbler (local concern)
•Rufous-crowned sparrow (local concern)
•Western skink (local concern)
•Monarch butterflies (local concern)
The recent survey effort added to this list with the following species observed:
•Bats (Mexican free-tailed, hoary-local concern)
•Mountain lion (local concern)
The results of the September 2017 surveys provide a small sample of wildlife utilizing
Cerro San Luis Natural Reserve. A true inventory of species would require a long-term
survey and monitoring effort occurring over multiple seasons and conditions to
thoroughly understand and document wildlife usage of the Reserve. The City has set up
remote sensing camera stations and they intend to monitor those over a period of time.
The results of species captured by these cameras will further inform the City about the
diversity of wildlife using the Reserve.
The Reserve is heavily used by the public including occasional unauthorized nighttime
use, as confirmed during the 2017 surveys. As such, baseline disturbance has been
occurring on the Reserve. Impacts to wildlife by authorizing extended hours on the
Reserve are largely unknown but may include:
•Disruption of normal foraging for nocturnal and crepuscular species (i.e., those
that forage at or just after sundown);
•Increased energy usage as a result of disturbance;
•Disruption of breeding or nesting behaviors;
•Increased risk for predation for species flushed by human activity; and
•Abandonment of habitat near recreational uses.
The amount of disturbance and impacts to wildlife species as a result of nighttime
activity will be variable depending on the level of use, the type of uses, and the season
of use. For example, hikers that may linger at certain locations will likely cause more
disturbance than a single mountain bike passing by quickly. The addition of dogs,
especially if not kept on leash, would increase the level of disturbance to wildlife using
the Reserve. Of particular concern for all species, uses during breeding, nesting, and
rearing seasons for wildlife on the Reserve may have the greatest level of impact.
Maternal roosts of bats are particularly sensitive to disturbance and parents may
abandon young/roosts during this season.

Generally speaking, the time of year that most species are breeding, nesting, and
rearing is from February through early September. A range of seasons for some of the
species known to or expected to occur are listed below.
Mountain lion (Puma concolor)
Females may be in estrus at any time of the year, but in California, most births probably
occur in spring. Gestation period 82-97 days; litter size is 2-4 (range 1-6). Young become
independent during second year. Habitat includes caves and other natural cavities, and
thickets are used for denning.
Gray fox {Urocyon cinereoargenteus)
Breeding occurs February to March, with most births occurring in April, following a
gestation of approximately 63 days. Average litter size is 4 pups; range 2-7. Young are
weaned at 4 weeks and become independent at around 10 months. Habitat includes
dens in natural cavities, in rocky areas, snags, logs, brush, slash and debris piles,
abandoned burrows, and under buildings. Nest material is usually dry grass, leaves, or
shredded bark.
Townsend's big eared bat {Corynorhinus townsendii)
Breeding occurs November to February; gestation lasts 56-100 days. Births occur in May
and June, peaking in late May. A single litter of one is produced annually. Young are
weaned in 6 weeks and fly in 2.5-3 weeks after birth. Maternity roosts are found in
caves, tunnels, mines, and buildings. Small clusters or groups (usually fewer than 100
individuals) of females and young form the maternity colony. Maternity roosts are in
relatively warm sites.
Pallid bat (Antrozous pallidus)
Breeding occurs October to February with fertilization delayed; gestation is 53-71 days.
Young are born from April-July, mostly from May-June. Litter size is 1-3. The altricial
young are weaned in 7 weeks, and are observed flying in July and August. Habitat
includes day roosts in caves, crevices, mines, and occasionally in hollow trees and
buildings. Roost must protect bats from high temperatures. Night roosts may be in more
open sites, such as porches and open buildings.
White-tailed kite (Elanus leucurus)
Breeding occurs February to October, with peak from May to August. Female only
incubates, for about 28 days. Average clutch 4-5 eggs, range 3-6. Young fledge in 35-40
days. Habitat includes a nest of loosely piled sticks and twigs and lined with grass, straw,
or rootlets. Nests are often placed near top of dense oak, willow, or other tree stand;
usually 6-20 m (20-100 ft) above ground. Nests are located near open foraging area.

Mule deer {Odocoileus hemionus)
TERRA · VERDE
Environmentol Consulting
Breeding occurs January to April; gestation period is about 200 days. Does can give birth
to one, two, or three fawns, though triplets are rare. Fawns are born in late spring to
mid-summer. Fawns are weaned in the fall after about 60-75 days and continue to stay
with their mothers during the first year. Habitat includes foothills and mountain peaks.
Monarch butterfly (Danaus plexippus)
Breeds in spring. Young emerge 4 days after eggs are laid, with 2 weeks as a caterpillar,
and 10 days as a chrysalis. Habitat includes open fields and meadows with milkweed.
Overwintering habitat based on microclimate that provides wind protection.
Oak titmouse {Baeolophus inornatus)
Breeds March to July, with peak activity in April and May. Lays 3-9 eggs, usually 6-8, with
an incubation of 14-16 days. Altricial young tended by both parents in nest about 20
days, and for another 3-4 weeks after leaving the nest hole. Habitat includes nest of
grass, moss, mud, hair, feathers, and fur in woodpecker hole, natural cavity, or nest box.
Sometimes partially excavates own cavity. Nests up to 10 meters (32 feet) above
ground, but usually lower. Often breeds near water.
Red-tailed hawk {Buteo jamaicensis)
Breeds March to July, peaking in May and June. Clutch of 2-5 eggs, usually 2-3, laid in
March and April. Incubates 28-32 days. Semialtricial young fledge in 40-45 days. Habitat
is usually placement of nests in large trees near openings, in older, mature forests,
especially riparian deciduous habitats. Occasionally nests on cliffs or low ledges. Nests 9-
21 meters (30-70 feet) above ground in trees, higher on cliffs.
Red-shouldered hawk (Buteo lineatus)
Breeds February to July, with peak activity April and May. Clutch size 1-5 eggs, usually 3.
Young are independent in 17 to 19 weeks. Habitat includes nests in dense riparian
habitats. Builds a nest of sticks about half way up in a tall tree. Nest located next to main
tree trunk, or on old nests of squirrels, hawks, or crows; lined with strips of bark, dry
leaves, and sprigs of evergreens.
Western screech owl (Megascops kennicottii)
Breeds early February to June. Eggs mostly laid in April. Clutch size 1-8, usually 3-4.
Incubation 21-30 day, with nestlings fledging at 28-35 days. Obligate secondary cavity
nester. Habitat includes uses such as abandoned woodpecker hole, or other cavity in
snag, hollow tree, log, stump; occasionally uses nest box. Nest usually 4.6 to 18 m (15-60
ft) above ground.
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
Barn owl (Tyto alba)
TERRA · VERDE
Environmentol Consulting
Breeds January to November. Clutch size 3-11, usually 5-7. Incubation 21-24 days, with
young fledging at 52-70 days. Habitat is usually nesting on ledges, crevices, or other
sheltered areas of cliffs or human-made structures. Also nests in cavities in trees or
snags, burrows, culverts, or nest boxes.
Summary
The information provided is from a limited survey effort during one season of the year,
and as such, does not provide a robust analysis of wildlife usage of the Reserve. It is
likely that nighttime use will impact wildlife occurring on the Reserve, but the extent
and severity of that impact is unknown. Efforts to reduce use during the breeding,
nesting, and rearing periods of a year will lessen potential impacts to wildlife.

RE: Summary and Results of Wildlife Surveys at Cerro San Luis Natural Reserve,
City of San Luis Obispo, California
The City of San Luis Obispo (City) is considering extending the hours of use for one or
more City open space properties. Of specific interest is Cerro San Luis Natural Reserve
(Reserve) based on location, surrounding land uses, proximity to traffic, and amount of
use currently occurring on the Reserve. Terra Verde Environmental Consulting, LLC
(Terra Verde) was retained to assist the City with gathering data that will help inform
the City’s decision-making process for extended use hours of the Reserve. Initial surveys
were completed in 2017 by Terra Verde prior to the implementation of the City’s Night
Time Use Pilot program. Following the pilot program, Terra Verde implemented once a
month nighttime sampling to collect additional information about wildlife utilizing the
Reserve.
General Survey Methodology
Terra Verde biologists Brooke Langle and Halden Petersen conducted the first survey
following the beginning of the pilot program on October 29, 2018. The survey was
conducted along an approximate 2-mile loop along the Lemon Grove Loop Trail and the
M Trail with a visual scan of surrounding areas. During this survey, spotlighting for
wildlife was conducted using binoculars for identification. Additionally, electronic game
calls were set up at approximately six locations, spread intermittently along grassland,
shrubs, and wooded areas.
Three subsequent surveys were conducted on December 05, 2018, January 24, and
February 28, 2019 by Terra Verde biologists Riley Chestnut and Sara Snyder. Spotlighting
was conducted during all three survey periods along the Lemon Grove Loop and M Trail.
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
Environmental conditions during the surveys consisted of the following:
• October 29, 2018: Clear skies, 10-15 mile per hour (mph) winds, and
temperatures ranging between 60 and 65° Fahrenheit (F).
• December 05, 2018: Partially clear skies, 5-10 mph winds, and temperatures
ranging between 52 and 56° F.
• January 24, 2019: Cloudy, 5-10 mph winds, and temperatures ranging between
57 and 59°F.
• February 28, 2019: Partially clear skies, 15-20 mph winds, and temperatures
ranging between 55 and 60°F.
During the surveys, all species observed directly and/or indirectly (e.g., tracks, scat, call,
remains, and acoustic observation) were documented.
Wildlife Results
Environmental conditions and anthropogenic activity levels varied between the October
29, 2018 and February 28, 2019 survey efforts. The first survey consisted of clear skies
and significantly warmer weather, while the subsequent surveys occurred with higher
cloud cover and cooler temperatures. Although no hikers were encountered on
December 05, 2018, increased human activity was observed during the February survey,
including one mountain biker and numerous hikers.
Spotlighting
The biologists walked the trail system, stopping frequently to scan up the surrounding
area with high powered flashlights or spotlights. Any eyeshine detected was
investigated and binoculars were used to identify species. The area around the
eucalyptus tree line, the coast live oak woodland higher up the mountain, and the seep
appeared to have more wildlife activity than the more open grassland habitats. The
surveys occurred up to three hours after sunset.
The following species were observed during the first spotlighting effort: barn owl (Tyto
alba) responding to game call, mule deer (Odocoileus hemionus), woodrat (Neotoma
sp.), and 2-3 unidentified eyeshine’s, possibly large canines or felines.
The second spotlighting effort resulted in observing: two deer mice (Peromyscus
maniculatus), two mule deer, and one sharp-shinned hawk (Accipiter striatus).
The third spotlighting effort resulted in detecting two great-horned owls (Bubo
virginianus) by sound, as well as directly observing three deer mice and one mule deer.
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
Lastly, the February spotlighting effort resulted in observing: two barn owls, one
woodrat, and one desert cottontail rabbit (Sylvilagus audubonii).
Wildlife Species Discussion
There are numerous wildlife species that inhabit the Reserve and surrounding areas of
Cerro San Luis. There is a potential for special-status species to occur, however, there
are limited records of sensitive species occurring within the Reserve. The report
prepared for the City in 2004 noted the following sensitive species:

• Ornate shrew (local concern)
• Raptors (local concern)
• Yellow-rumped warbler (local concern)
• Rufous-crowned sparrow (local concern)
• Western skink (local concern)
• Monarch butterflies (local concern)
A 2017 survey effort by Terra Verde added to this list with the following species
observed:
• Bats (Mexican free-tailed, hoary – local concern)
• Mountain lion (local concern)
The results of the October 2018–February 2019 surveys provide a small sample of

Oak titmouse (Baeolophus inornatus)
Breeds March to July, with peak activity in April and May. Lays 3-9 eggs, usually 6-8, with
an incubation of 14-16 days. Altricial young tended by both parents in nest about 20
days, and for another 3-4 weeks after leaving the nest hole. Habitat includes nest of
grass, moss, mud, hair, feathers, and fur in woodpecker hole, natural cavity, or nest box.
Sometimes partially excavates own cavity. Nests up to 10 meters (32 feet) above
ground, but usually lower. Often breeds near water.
Red-tailed hawk (Buteo jamaicensis)
Breeds March to July, peaking in May and June. Clutch of 2-5 eggs, usually 2-3, laid in
March and April. Incubates 28-32 days. Semialtricial young fledge in 40-45 days. Habitat

young fledging at 52-70 days. Habitat is usually nesting on ledges, crevices, or other
sheltered areas of cliffs or human-made structures. Also nests in cavities in trees or
snags, burrows, culverts, or nest boxes.
Summary
The information provided is from a limited survey effort during primarily the winter
season, and as such, does not provide a robust analysis of wildlife usage of the Reserve.
Further, as documented by 2017 survey efforts by Terra Verde, unauthorized nighttime
use was ongoing prior to the implementation of the City’s pilot program for nighttime
hiking. As such, it is likely that nighttime use will have an effect on wildlife occurring on
the Reserve, but the extent and severity of that effect is unknown. Efforts to reduce use
during the breeding, nesting, and rearing periods of a year will lessen potential impacts
to wildlife.

RE: Summary and Results of Wildlife Surveys at Cerro San Luis Natural Reserve,
City of San Luis Obispo, California
The City of San Luis Obispo (City) has conducted a pilot program for extending the hours
of use for Cerro San Luis Natural Reserve (Reserve). This Reserve was selected based on
location, surrounding land uses, proximity to traffic, and amount of use currently
occurring on the Reserve. Terra Verde Environmental Consulting, LLC (Terra Verde) was
retained to assist the City with gathering data that will help inform the City’s decision-
making process for extended use hours of the Reserve. Initial surveys were completed in
2017 by Terra Verde prior to the implementation of the City’s Nighttime Use Pilot
program. Following the pilot program, Terra Verde implemented once a month nighttime
sampling in the winter of 2018 – 2019 and 2020 – 2021 to collect additional information
about wildlife utilizing the Reserve. Below is a summary of the results of the 2020 – 2021
survey period.
Survey Methodology
Terra Verde biologists conducted four surveys that consisted of acoustic monitoring for
bats and spotlighting for wildlife. For acoustic monitoring, a Pettersson D500x bat
detector was placed along the southern margins of the eucalyptus grove near the
intersection of Carriage Road Trail and Lemon Grove Loop . Acoustic recording occurred
from just before sunset to approximately an hour after sunset. Following the survey, the
recordings were analyzed using SonoBat US West (Szewczak) and recorded calls were
identified to species level when possible.
Spotlighting surveys were conducted along an approximate 2-mile loop consisting of the
Lemon Grove Loop Trail and the M Trail. Surveyors walked the trail, stopping frequently
to scan the surrounding area with high powered flashlights or spotlights. Any eyeshine
detected was investigated with binoculars to identify species. All species observed
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
directly and/or indirectly (e.g., tracks, scat, call, remains, and acoustic observation) were
documented. Survey details are summarized in Table 1 below.

Survey Results
Anthropogenic activity levels within the Reserve varied between the December 17, 2020
and March 2, 2021 survey efforts. High recreational use was observed during the
December and January surveys. On December 17, the parking lot at the trailhead was full
and large groups of hikers and mountain bikers were encountered throughout the survey
duration. Recreational use was lower during the Febru ary and March surveys. Use
consisted primarily of individuals or small groups of between two to four hikers, runners,
and/or mountain bikers.
Wildlife detections were low during the four surveys. Large and medium sized mammals ,
black-tailed deer (Odocoileus hemionus columbianus) and bobcat (Lynx rufus), were
detected only during the February 16th survey when recreational use was low. Bats were
detected either through acoustic monitoring or visually during three out of the four
surveys. One California Species of Special Concern (CSC), western mastiff bat, was
detected by the acoustic monitoring. In addition, an unidentified species of woodrat was
observed. Certain species of woodrats are California Species of Special Concern.

Discussion
The results of the three survey periods completed by Terra Verde (2017, 2018 – 2019, and
2020 – 2021) provide a small sample of wildlife utilizing Cerro San Luis Natural Reserve. A
true inventory of species would require a long-term survey and monitoring effort
occurring over multiple seasons and conditions to thoroughly understand and document
wildlife usage of the Reserve.
The Reserve is heavily used by the public including occasional unauthorized nighttime use
prior to the City’s pilot program, as confirmed during the 2017 surveys. As such, baseline
disturbance has been occurring on the Reserve. Impacts to wildlife by authorizing
extended hours on the Reserve may include:
• Disruption of normal foraging for nocturnal and crepuscular species (i.e., those
that forage at or just after sundown).
• Increased energy usage as a result of disturbance.
• Disruption of breeding or nesting behaviors.
• Increased risk for predation for species flushed by human activity .
• Abandonment of habitat near recreational uses.
3765 South Higuera Street, Suite 102 San Luis Obispo, CA 93401
The amount of disturbance and impacts to wildlife species as a result of nighttime activity
may be variable depending on the level of use, the type of use, and the season of use. For
example, hikers that linger at certain locations will likely cause more disturbance than a
single mountain bike passing by quickly. The addition of dogs, especially if not kept on
leash, would increase the level of disturbance to wildlife using the Reserve. Wildlife can
be particularly sensitive to disturbances during breeding, nesting, and rearing season. For
example, maternal roosts of bats are particularly sensitive to disturbance and parents
may abandon young/roosts during this season. The time of year that most species are
breeding, nesting, and rearing is from February through early September. Therefore,
increased use during this period may have the greatest negative impact on wildlife within
the Reserve.
Summary
The results of these limited survey efforts, primarily outside of the breeding, nesting, and
rearing season for wildlife, does not provide a robust analysis of wildlife usage of the
Reserve. Further, as documented by 2017 survey efforts by Terra Verde, unauthorized
nighttime use was ongoing prior to the implementation of the City’s pilot program for
nighttime hiking. As such, it is likely that nighttime use will have an effect on wildlife
occurring on the Reserve, but the extent and severity of that effect is unknown. Efforts to
reduce use during the breeding, nesting, and rearing periods of a year will lessen potential
impacts to wildlife.
